Abstract
Abstract Compound gases having fluorine as a constituent are combined with helium in an enclosure within an optical cavity and are subjected to the discharge of electrical energy. The electric discharge dissociates the compound gas providing fluorine atoms and excites the fluorine providing a population inversion of electronic energy levels. The fluorine lases in the optical cavity producing a visible beam of laser energy at 7039, 7129 and 7204 Angstroms.
